javascript - 避免在 RequireJS 主文件和 r.js 构建文件中重复 "paths"配置？

Question

这是(部分)我的文件夹结构:

• 节点测试
  • bower_components
  • build
  • 公开
    • main.js
  • build.js

使用 r.js -o build.js 运行优化器，以下配置工作正常:

// main.js file
requirejs.config({
    baseUrl: '../bower_components',
    paths: {
        'domready': 'domready/ready',
        'jquery': 'jquery/jquery',
    }
});

requirejs(['domready', 'jquery'], function (domReady, $) {
    domReady(function () {

    });
});

// build.js file
({
    baseUrl: "bower_components",
    name: "./almond/almond",
    include: "./../public/main",
    out: "build/main.js",
    paths: {
        'domready': 'domready/ready',
        'jquery': 'jquery/jquery',
    },
    preserveLicenseComments: false
})

但是，如果我删除 build.js 中的 paths 配置，它就不再起作用了:

Tracing dependencies for: ./almond/almond Error: ENOENT, no such file or directory 'C:\Users\Marco\Documents\Progetti\nodejs-opt\bower_components\domready.js' In module tree: ../public/main

Error: Error: ENOENT, no such file or directory 'C:\Users\Marco\Documents\Progetti\nodejs-opt\bower_components\domready.js' In module tree: ../public/main

at Object.fs.openSync (fs.js:427:18)

我想保持干爽，避免两次添加依赖项。这可能吗？

如果您想使用运行时代码中的相同配置来查找您的库的位置，您可以使用 mainConfigFile选项:

...if you prefer the "main" JS file configuration to be read for the build so that you do not have to duplicate the values in a separate configuration, set this property to the location of that main JS file. The first requirejs({}), require({}), requirejs.config({}), or require.config({}) call found in that file will be used.

像这样:

({
    baseUrl: "bower_components",
    mainConfigFile: '/some/path/main.js', // adjust path as needed
    name: "./almond/almond",
    include: "./../public/main",
    out: "build/main.js",
    preserveLicenseComments: false
})
